Maybe a new discovery?
I haven't found anything else about the HID device thing, but I did find that if I extract the .exe firmware update, and copy firmware.sb to my devices root, it seems to perform the update, I can't really tell because it's the same. When I unplug it, it says to not disconnect for a while, and then it goes back to normal.
I'm interested in decrypting the firmware, but I have no idea where to start. Can anyone point me in the right direction? I want to start getting into this sort of thing, but I have no idea where to start.
